This compact guide lays out the basics of Intelligent Design, popularly known as ID. William Dembski, the dean of the intelligent-design movement, and Sean McDowell especially target readers whose understanding may have been confused by educational bias and one-sided arguments and attacks. Commonsense and no-nonsense, with pointed examples, the authors explain: the central theories of ID, showing why the presence of information and meaningful complexity require the involvement of intelligence; why ID adheres to the scientific method and is a valid field of scientific inquiry; why scientific evidence increasingly conflicts with evolutionary theories; how both evolutionary theory and ID have religious/philosophical underpinnings, and why this causes so much controversy; and, how both systems of thought have radical implications for our culture - and what readers can do about it. Clarifying crucial issues, this key resource gives nonspecialists a solid grasp of one of today's foundational religious-scientific-cultural concepts.
